I! 'o all whom 'it' may concern.

Be it known that We, iii-Timer; E. Dehner and WILLIAM il. OSBORN, citizens of the United States., residing,` at Healy, in the county of Lane.y State ci" lansas,havc invented a newand useful Air-Supplying Attachment for larbureters, of which the following is a specification.

The present invention reletesyto improvements in air supplying attachments for carbureters., one object of the invention, being),r the provision or" an attachment adapted to he .opernhly connected to receive air through the crank case of an explosion engine, and to deliver the saine to the zrir intake of the cerhureter to be mined to' form carlnueted air to supply theengine, the drawing of the air through 'the crank case providing;- for cooling the hearings therein and also removing any volatile gases therefrom due to the heating of the lubricating oil. or the escape of the Carhnreted air from the power cylinder. l further object of the present invention, is the provision of means adapted to be attached to or in communication with the crank case which will prevent the mingling of the lubricating' oil with the air directed to the carbureter; A

With the foregoing and other objects in view which will appear as the description proceeds, the. invention resides in the combination and arrangement 'of parts and in the details of construction hereinafter described and claimed1 it being understood that changes inthe precise embodiment of the invention herein diselosed can he made within the scope of what is claimed without de parting, from the spirit of the invention.

ln the drawings,-4l}`i.;:r1re lis an exterior view in elevation of the plate adapted to he attached to the crankcese of a i Ford ann tomobile motor. Figi?, is rear elevation ther/eci?, Fig. 3 is a section taken on line Fig. is a diagrammatic side elevation of a F ord automobile engine or motor with the' present invention applied thereto. f

Referriner to the drawings. and morel particularly to Figs. l through 4. the numeral l' designates the explosion engine, which is provided with the an' intake 2 at the for- Werd end of the crank or base thereof.

the rear end 3 which forms. in the Ford i engine` the clutch casino that is in communicat-ion with the crank case ofthe engine is 21de ated to have the upper end thereof sealed by means oiE the two plates hand, Y

which are connected together and to the en `gine hy means of the bolts or screws.

The plate et is apertured and such ener ture is covered by the oil. deliectingg hood 5 which is adapted to incline toward the rear of the motor casing end to direct the air into the open end of the rectangular casing.; 5 connected to and carried hy the plete i" which is similar in shepeto the platee and .is adapted to be disposed co-extensive thereto. as clearly illustrzited'in Fig, f

Disposed transversely of and within the casing (i is a. cylindrical air directing ineinber S, provided with the port i) longitndifnallv thereof, said portl beine: disposed' toward the upper face of the casing 4S so 'that the least possible danger ot' lubricant enter in;r the directingmember 8 and consequently into they pipe l0 would he the result.

rl'he pipe 10 is in communication with the air intake oi the carhnreter C.

lt will thus be seen that as the power cylinders (not shown) of an explosion engine, 'are operating', that nir will he drawn in through the intake 2 and throng-h the cra-nk. case of the engine and inally into theport 9 of the air directingr member 8 and there to loe directed through the pipe l0 to the take of the carbureter (l and the same beine; here mixed with the liquid if'ud i earbureted air which is directed'throu,f'gill1- l the intake manifold l) to the explosion ellenibers of the engine. Bv this ineens itgvill be seen that the cool air enteringa the intake 2 will assist in 'cooling the bearings of the crank shaft and power pistons thereof and that such air will be slightly .varinedso as to assist in the formation of the cerhnretei air. liv this means, the volatile Jises within the crank :ase from the lubricating oil and also due to the leakage in the compression' from the enrrinecvlinders will he thoroughlv mixed with the air before entering` the chamber (L the dedector 5 preventing the liquid oil or lubricant from entering,F

the same so that the volatile ,enses with-the ubrican; Wi. be removed an@ inaiy consinned with die cai'bmte What is claimed is:
